Caution To avoid permanent damage to the NI 6587, disconnect all signals
connected to the NI 6587 before powering down the module, and connect signals
only after the adapter module has been powered on by the NI FlexRIO FPGA
module.
Caution Connections that exceed any of the maximum ratings of any connector on
the NI 6587 can damage the device and the chassis. NI is not liable for any damage
resulting from such connections.
Note If you design a custom cabling solution with the InfiniBand connector
(779157-01) and the SHB12X-B12X LVDS shielded cable (192344-01), the NI 6587
pinout is reversed at the end connector. For example, the signal shown on pin 1 maps
to pin 73 in the pinout at the end connector.

NI 6587 Component-Level Intellectual Property (CLIP) on page 9
NI 6587 Component-Level Intellectual Property
(CLIP)
The LabVIEW FPGA Module includes component-level intellectual property (CLIP) for HDL
IP integration. NI FlexRIO devices support two types of CLIP: user-defined and socketed.
•User-defined CLIP allows you to insert HDL IP into an FPGA target, enabling VHDL
code to communicate directly with an FPGA VI.
•Socketed CLIP provides the same IP integration of the user-defined CLIP, but also allows
the CLIP to communicate directly with circuitry external to the FPGA. Adapter module
socketed CLIP allows your IP to communicate directly with both the FPGA VI and the
external adapter module connector interface.
The following figure shows the relationship between an FPGA VI and the CLIP.

or deserializes, respectively, the signal by a
factor of 10 by default. During acquisition, the
NI 6587 reads or writes ten bits of data per
channel to or from the ISERDES or
OSERDES blocks. All OSERDES and
ISERDES blocks are set to double data rate
(DDR) mode.

parallel data at high speeds. You can access
the LVDS data and direction lines using a U16
data type, you can access the LVDS PFI lines
using a U8 data type, and you can access the
single-ended PFI lines using a Boolean
control. In the U8 data type, the top four bits
are unused. Each LVDS line, PFI line, and
clock output is connected to an OSERDES or
ISERDES block that serializes or deserializes,
respectively, the signal by a factor of six by
default. Therefore, with every regional clock
cycle, the NI 6587 reads or writes six samples
to or from the ISERDES or OSERDES
blocks. All OSERDES and ISERDES blocks
are set to double data rate (DDR) mode.

Cables
Caution You must operate the NI 6587 with shielded cables and shielded
accessories to ensure compliance with the EMC requirements defined in the NI 6587
Specifications. Do not use unshielded cables or accessories unless they are installed
in a shielded enclosure with properly designed and shielded input/output ports and
are connected to the NI 6587 using a shielded cable. If unshielded cables or
accessories are not properly installed and shielded, the EMC specifications for the
NI 6587 are no longer guaranteed.

NI 6587 Getting Started Guide | © National Instruments | 15

Use a shielded 50 Ω coaxial cable with an SMA plug end to connect to the PFI 0 and
CLOCK IN connectors on the NI 6587 front panel. Use the NI SHB12X-B12X shielded cable
(NI part number 192344-01) or the NI SHB12X-H3X24 differential flying-lead cable (NI part
number 196236-1R5) to connect to the DDC connector. You can also connect the
NI SMA-2164 accessory to the NI 6587 through the SHB12X-B12X shielded cable for testing
and debugging.
Note If you design a custom cabling solution with the DDC connector (779157-01)
and SHB12X-B12X shielded cable (192344-01), the NI 6587 pinout is reversed at
the end connector. For example, the signal shown on pin 1 maps to pin 73 at the end
connector.
The following NI cables and accessories are not properly shielded for EMC-compliant use
with the NI 6587:
• NI SMA-2164 accessory
• NI SHB12X-H3X24 differential flying-lead cable
Note Whether you use NI cables and accessories or design your own, terminate
cables properly to avoid improper measurements caused by signal reflections,
overshoot, and undershoot.
Accessories
The NI SMA-2164 test fixture is a breakout box for differential signals. This fixture provides
an easy way to connect to other devices for testing and debugging.
The following figure shows how to connect the differential DDC connector to the
NI SMA-2164, using the NI SHB12X-B12X cable. For more information about using the
NI SMA-2164, refer to the NI SMA-2164/2165 Test Fixture User Guide.

A flying lead cable, the NI SHB12X-H3X24, is also available for differential signals. This
cable offers connectivity similar to that found on a typical logic analyzer, so you can use it in
logic analyzer-type applications. This cable is shown in the following figure.

Custom Accessories
If you are creating a custom accessory to use with a DUT with a VHDCI DDC connector, you
can purchase the mating connector for the VHDCI cable from NI. For more information about
creating these custom accessories, refer to the Interfacing to the NI Digital Waveform
Generator/Analyzer using the VHDCI Connector application note.
Visit ni.com/info and enter the info code rdinwa to download this note.
If you are designing a custom accessory to use with a device that uses an InfiniBand
connector, you can also purchase this connector from NI.
Note If you design a custom cabling solution with the DDC connector (779157-01)
and SHB12X-B12X shielded cable (192344-01), the NI 6587 pinout is reversed at
the end connector. For example, the signal shown on pin 1 maps to pin 73 at the end
connector.
For more information about connecting I/O signals on your device, refer to the NI 6587
Specifications.

Clocking
The clocks on the NI 6587 control the sample rate and other timing functions on your
NI FlexRIO system. The following figure shows the NI 6587 clock sources routed through the
crosspoint switch. The Generation Bank I/O clock, PFI Bank I/O clock, and Global clock are
all sourced by the crosspoint switch. The Acquisition Bank I/O clock can be sourced from the
crosspoint switch or accessed directly through the Strobe Bypass path.
Note Only the Acq_IO_Clock_Source signal can use the STROBE Bypass path. If
Acq_IO_Clock_Source is set to Strobe Bypass, then Gen_IO_Clock_Source,
PFI_IO_Clock_Source, and IO_Module_Clock_1_Source cannot be set to Strobe
From Crosspoint Switch.

In software, each clock output terminal is accessed with a U8 data type. The following table
shows the values of the crosspoint switch clock options.
Table 7. Clock Values
Value Clock Option
0Tristate—Output disabled (high impedance).
2Sync Clock (PXI Express Only)—Clock from PXI Express backplane. You can
select PXI_CLK10 or DStarA in the Details category of the IO Module Properties
dialog box.
3Adapter Module Onboard Clock—Clock generated from the Si570 clock chip.
4Strobe From Crosspoint Switch—LVDS STROBE signal from crosspoint switch.
Use this setting to route the LVDS STROBE signal to multiple I/O clocks.
5Strobe Bypass—LVDS STROBE bypasses the crosspoint switch. The propagation
delay of the Strobe Bypass exactly matches the propagation delay of the data
channels. This setting is ideal for source- synchronous applications.
